  • Page 29: 4.0 Media Converters

    Model 907 Video/Data Multiplexer – User’s Guide 4.0 Media Converters Model 907 media converter cards are PC/104 form-factor modules used to provide optical transmission of high-speed data signals (20-1500 Mbps), such as Ethernet, ECL/PECL for multi-beam sonar links, IEEE-1394 (widely known as “Firewire”) for digital cameras and digital high-definition video (SMPTE-292). Media converters may be deployed as standalone cards using a designated fiber or as CWDM versions that are optically multiplexed with a motherboard or other media converter cards.

  • Page 30: 907-Mc (10/100 Mbps Ethernet)

    The fiber link is limited to a length of 2 km when half-duplex mode is used, as per IEEE 802.3 standards. If the 907-MC card is configured to use full-duplex mode, the fiber link length is limited only by the optical budget.

In this way, the 907-GBES card behaves like a 907 motherboard or a 907 media converter. Each 907-GBES is fuse limited to 5.0 A for on-board current draw plus total current draw from the stacked cards.

    For example, if a 907-485 expansion card is assigned to data port 5, then the channel 5 RS-485/422 channel on the 907 card itself is disabled while the expansion card overrides it. Furthermore, the RS-232 channels (1-4) on the standard 907 card run on dual transceivers, so disabling one channel always disables a second channel, i.e.
